松辽盆地南部长岭断陷地震采集技术

A Cquisition Technique of Changling Depression of the Southern of Songliao Basin

针对长岭凹陷区复杂的表层及深层地震地质条件,从观测系统设计、高密度精细表层调查技术、虚反射分析、提高地震反射能量的激发技术、压制干扰的接收技术的研究,总结出了适合松辽盆地南部中央坳陷长岭凹陷区最佳的采集方法,很好地解决了采集中的技术难题,有效地提高了复杂地震地质条件下资料的品质。

In allusion to complicated the seismic geological conditions of the near surface and deep layer,the author studied the design of spread geometry,technique of high density surface survey,technique of ghost wave,technique of shooting to improve seismic energy,technique of receiving to decrease interference.Summarized a suit of optimal seismic acquisition technique adapt to Changling depression of center depression of the southern of Songliao basin.The papercan solve problem in seismic acquisition,desirable results were reached.
